I had replaced the fuse for the fog l;ights when I bought the car and it was working great for 3 weeks right up til the moment I had a store install my new stereo deck, a kenwood 208u, now the fuses are poping as soon as I put them in, what the heck do I do? I put in a 20 instead of a 15 and when I turned the fog lights on it didn't blow but it was drawing a lot of power, dimming the rest of the lights on the car si I pulled it right away and just left the fog light fuse out for now.

Yell at the guy that installed it because he obviously grounded something he shouldn't have?

 

It may be something as simple as the wrong bulbs in there. They should be 55 watt bulbs and some people put in 100 watt bulbs which can cause the fuse to blow. Just pick up some new bulbs and slap them in first. Also, make sure there isn't condensation forming in the fog light. The bulb grounds to the fog light housing.

 

yeah, unplug the bulbs, and put a fuse in, see if it blows.
